I have a few questions regarding a camera I bought today. I want to use it practically as a mediuim format camera for landscapes. It is a Meopta Flexaret. The questions I have are: When was it made? - if it's any help the lenses (TLR) are Meopta Anastigmat 1:3 f = 80mm serial: 80115236 and Meopta Mirar II 1:3,5 f=80mm serial: 2044291 Other question relate to it's operation and refer to the annotated picture below... thankyou to whoever answers this... How stiff is the focus slider supposed to be and how do I loosen it up? What is the lever with the red dot used for? i think it is a self timer but don't understand how to use it. and There is a little red circular window on the back of the body that is used to look at the numbers on the film when winding on... It has a sliver of normal light flowing through, does this matter with the backing paper of 120 film? one more, if anyone can give me any general tips for shooting a) with 120 film for the first time and b) with using TLR cameras, particularly with the problem of paralax. I know it's a lot to ask but hopefully at least some of it can be answered. Thanks VERY much in advance. Picture below.
